What If
they brought out a NG-Mustang co-platformed Lincoln RWD coupe-cabrio with my imagined 700hp 5.0v8-EB + little electrics up front to fill that rôle BEFORE the Mustang debut (April'14)
and then
later brought out "regular" powered versions along with a (sport)sedan version?

thinking of a way that timing alone could provide a halo car/trim within the regular lineup instead of building a "folly" like another GT
(imho it should be easy to go a year-fraction without Mustang production while starting off the nextgen with the Lincoln - Mustang sales should be dismal anyway as word spreads about the new model's intro date)

meant for ^that to be a 2-door, but since both donors have 4-door-sized openings, didn't fight it.
price = 'just' $70-90k
